1-Phase 8 kW Hybrid Inverter (48 V, 2 MPPT, WiFi Plug Included)
The Deye SUN-8K-SG05LP1-AU is an 8 kW single-phase hybrid inverter designed for homes and small businesses that need more capacity than a standard 5–6 kW system. It manages solar, battery storage and the grid in one unit and supports low-voltage 48 V batteries, with a high 190 A charge/discharge rating for serious storage setups.
BSC Renewables can supply this inverter with the WiFi plug included and set up, so clients can monitor their system from the start.

Who Is This Inverter For?
The SUN-8K-SG05LP1-AU is ideal for:
- Larger homes with higher loads (ducted air-con, pools, EV charging, multiple fridges).
- Home-based businesses or small commercial tenancies on single-phase power.
- Households wanting to run larger battery banks and have stronger backup capability.
- Clients planning for future expansion of solar and storage rather than just “covering the basics”.
It offers more headroom than a 5–6 kW inverter, while still working on standard single-phase supply.
How the SUN-8K-SG05LP1-AU Works for You
Solar, Battery and Grid in One Unit
As a hybrid inverter, the SUN-8K-SG05LP1-AU manages:
- DC power from the solar panels
- Charging and discharging of the battery
- Import and export to the grid (and, in some modes, a generator)
In day-to-day use:
- Solar powers the home or business first.
- Excess solar charges the battery (up to 190 A).
- After dark or during cloudy periods, the battery can supply up to 8 kW of power before the system draws from the grid. au.deyeinverter.com
For your clients, that means less grid energy used and better use of the solar they produce.
Strong 48 V Battery Performance
Battery input features from the product datasheet are as follows:
- Battery type: Lead-acid or lithium-ion
- Battery voltage range: 40–60 V
- Max charging current: 190 A
- Max discharging current: 190 A
- Battery inputs: 1
- Charging strategy: Self-adaption to lithium BMS
What this means in practice:
- Supports a wide range of 48 V battery brands commonly used in Australia.
- High current capability suits larger battery banks and higher backup loads.
- Low-voltage architecture is well-suited to homes and small businesses from a safety and design perspective.
More Roof Options with 2 MPPTs and High PV Capacity
The SUN-8K-SG05LP1-AU gives plenty of room on the solar side:
- Max DC input power: 12,000 W
- Max PV access power (oversizing): 16,000 W
- Max PV input voltage: 500 V
- Rated DC input voltage: 370 V
- Start-up voltage: 125 V
- MPPT voltage range: 150–425 V
- Max operating PV input current: 26 + 26 A
- Max short-circuit current: 39 + 39 A
- MPPT trackers / strings: 2 / 2+2
Design benefits for BSC Renewables:
- Split panels across two or more roof orientations (e.g. north + west, or east + west).
- Better handling of partial shading by separating strings.
- Ability to oversize the array so the system still produces well in winter and cloudy conditions (within design and compliance limits).
Smart Time-Based Control and Load Shifting
The hybrid series supports six time periods for battery charging and discharging. au.deyeinverter.com+1
This lets you:
- Align battery behaviour with time-of-use tariffs (charge during solar and cheap periods, discharge during peak prices).
- Prioritise backup reserve if the client is in an area with frequent outages.
- Fine-tune how much energy is imported from, or exported to, the grid across the day.
BSC Renewables can configure these settings during commissioning, based on the client’s retailer plan and usage.
Designed to Scale – Up to 16 Inverters in Parallel
According to the datasheet and installation manual, the SUN-8K-SG05LP1-AU can be paralleled with up to 16 units for both on-grid and off-grid operation, with support for multiple batteries in parallel.
That means:
- Start with one 8 kW inverter now.
- Add more units in future for larger homes, big sheds or small commercial sites.
- Keep a consistent platform for monitoring, maintenance and spares.
Built for Australian Conditions
The AU datasheet lists the following environmental and compliance details:
- Operating temperature: –40 °C to +60 °C (with derating above 45 °C)
- Permissible ambient humidity: 0–100%
- Permissible altitude: up to 2,000 m
- Protection degree: IP65 (suitable for outdoor wall mounting)
